Analog Output Settings
The LS-7000 Series has analog voltage output according to the measured value. The
range of analog voltage output is between –10 and +10 V.
Setting Range
The following analog output settings are available.
• Scaling (reference value): In reference value mode (LIMITS), the deviation is output
as a positive or negative voltage based on the reference
value of 0 V. Select the scaling of deviation from the follow-
ing: 1, 2, 5, 10, 20, 50, 100, 200, 1000, 2000, 5000, and
10000
μm/V
• Scaling (threshold): In threshold mode, set the measurement values to be
output at +10 V and –10 V respectively so that the scaling
value will be decided.
The absolute value of the difference between these values
must satisfy the following condition.
{(Measured value at +10 V) – (Measured value at –10 V)} >

X
Value X varies with the minimum display unit.
The relationship between value X and minimum display unit
is shown below.

• Analog Update Mode The measured value after area calculation is output after
the analog scaling of the value regardless of whether the
display value is held or not. The function is ON/OFF
selectable.
• Output Waiting Voltage Set the output voltage of the LS-7000 Series when the
display shows “---.-----.” The items selectable are 0 V, 10.5
V, and HOLD (holding the previous voltage before the LS-
7000 Series began waiting for the result of the measure-
ment).
■ Scaling
There is a difference in scaling settings between the LS-7000 Series in tolerance mode
with reference values used and that with thresholds used. Refer to Tolerance Mode
(LIMITS) on page 4-56 for details.

● Tolerance Mode with Reference Value
Based on a reference value of 0 V, the
deviation is output as positive or negative
voltage. The voltage can be changed while
the result waiting status is “---.-----.” (See
